Mineral wool retains its shape a lot better than fiberglass or cellulose. It won't settle within just walls, leaving cold gaps along the very best plate. If there’s air infiltration, dampness will not compromise or degrade its thermal efficiency; and the fabric presents no food to aid microorganisms.

We then centered on the rock wool board products and solutions, due to the fact their greater density would decrease the wind-washing problem and their enhanced stiffness might aid the set up of the furring strips and siding.

That could suggest one” polyiso to the attic side with the studs, then mineral wool while in the wall (I’m assuming 2x4 walls below, When you've got 2x6s you require thicker foam to maintain the exact same ratio of batts to foam as well as ratio could be the important component) and you’re very good to go. For those who don’t wish to use rigid foam around the attic facet on the partitions, then I’d tack up some breathable housewrap (don’t use poly here!), then batts, And that i’d use a smart vapor retarder like MemBrain on the interior beneath the drywall. If this doesn’t sound like That which you’re endeavoring to do, publish a drawing displaying where by you want to insulate to help you everyone below know what we must know to be able to make it easier to.

Considering that the two heating and cooling manifest for prolonged durations in blended-humid climates, it might be difficult to decide the right process for humidity control. To add to the confusion, The American Modern society for Heating, Refrigeration and air con engineers (aSHrae) plus the Electrical power and environmental Constructing association (eeBa) recommend that wall programs be allowed to dry towards the inside or exterior surroundings in blended-humid climates and, if possible, allow for some drying in each Instructions." Can they ever fail because of distinctive RH problems than These described ?

Monthly bill - Thanks for the quick reaction! Do you're thinking that there'll be any dampness challenges installing the mineral wool insulation directly to the bottom side from the sub floor (no vapor retarder between sub ground and mineral wool) and after that making use of a layer of latex paint on the mineral wool? My knowledge is the fact mineral wool by itself acts as being a vapor retarder because of its density.

I concur with all that Monthly bill explained and hope that you'll be not overthinking this. In attics like yours there is an easy and economical solution: Pull out the old insulation, put a lot of work into air sealing the ceiling in the attic, and blow in as much insulation as you can afford, with blocking and vent baffles on the eaves to prevent wind washing and maintain air move to your ridge vent.

So now I'm click here considering critically about both of those the “breathable house wrap” and “sensible vapor retarder” references you lifted. I'm attaching several sketches and photographs that will help indicate the challenge regions I want to handle:
